<p>PROBLEM TO BE SOLVED: To appropriately adjust a focus by restraining misalignment of a focus detection position caused by chromatic aberration of a photographing lens.SOLUTION: A digital camera 10 includes: an AF sensor module 32 having spectral sensitivity characteristics over a wavelength region of visible rays to infrared rays; a photometric sensor 34C; a photometric part 34 that has sensitivity in a visible ray wavelength region and does not have sensitivity in an infrared ray wavelength region; and an infrared ray detection part 13 having sensitivity in the infrared ray wavelength region. A correction value for correcting positional misalignment of focusing caused by chromatic aberration of a defocus amount is calculated, on the basis of a ratio of a pixel signal of R, G, B outputted from the photometric sensor 34C of the photometric part 34 to an infrared signal outputted from the infrared ray detection sensor 13B of the infrared ray detection part 13.</p> |
